Engine runs hot when idle

Hi,

If this only happens when sitting still, it sounds like an issue. When the vehicle starts to overheat, pay attention to see if the fan turns on.

Take a look through this link. It explains how a cooling fan works.

If the fan does not turn on, follow these directions.

Also, check fuses 1 and 2 in the under hood fuse box. Both are 30 amp and power the cooling fan. See pic 1

Let me know if it doesn't turn on or if you have other questions.
